Regular grammars

Regular grammars are a way of describing simple patterns in strings of symbols, often used in computer science for designing algorithms, programming languages, and text processing. They consist of a set of rules that generate or recognize patterns by replacing symbols with other symbols or sequences, following specific structures. These grammars are limited to straightforward, linear patterns, making them efficient for tasks like tokenizing text or validating simple formats. Essentially, regular grammars provide a formal framework for defining predictable, rule-based sequences of characters or symbols.
